Terminology can be ambiguous here; there is no universal standard for how to describe antennas. That said, here are some heuristics: If someone says, e.g., “a 20-meter dipole”, they mean an antenna which is for the 20-meter band, i.e. almost 10 meters long from end to end (because a full-size dipole has an electrical …

WebA height of 1/8 to 1/10 wavelength is often used for effective NVIS. On the 40-meter band a dipole elevated just 4-meters (13 feet) above ground can provide very effective NVIS propagation in a radius of several hundred miles. The precise height above ground for the very best NVIS performance is not a well-agreed value.
Web5 sep. 2024 · Thirty two feet should be more then adequate to see an improvement, if you want to go higher then you need to look into a different support system.
